我刚刚将 Sqlite3 作为依赖项添加到我的项目(在服务器端)，当我尝试捆绑服务器代码以在生产中部署时，webpack 现在会生成一些错误。

最佳答案
您只需在 webpack 中将 sqlite3 指定为外部模块，这样它就不会被捆绑/解析。这是必需的，因为它是 native /二进制包。
只需将以下内容添加到您的 webpack 配置中:
externals: {
sqlite3: 'commonjs sqlite3',
},
包裹webpack-node-externals对所有 node_modules 执行相同的操作也可能会有所帮助。
关于node.js - 使用 Webpack 捆绑 Sqlite3 导致编译错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/65297136/
